JACOB C. RUBEL, OF EMMETSBURG, IOWA.

ADJUSTABLE WINDOW-SCREEN.

Application filed December 23, 1914, Serial No. 878,655. Renewed July26, 1916.

To all whom it may concern:

Be it known that I, JAooB C. RUBEL, a citizen of the United States,residing at Emmetsburg, in the county of Palo Alto, State of Iowa, haveinvented certain new and useful Improvements in Adjustable Window-Screens; and I do hereby declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same.

This invention relates to window screens and has special reference to ascreen adjustable both for width and height so that it may fit anywindow opening whether the sash be raised to its full extent or somewhatlowered.

The principal object of the invention is to improve and simplify thegeneral construction of devices of this character.

A second object of the invention is to provide a collapsible windowscreen wherein the members, which slide with reference to each other,may be constructed of tubular metal.

With the above and other objects in view the invention consists ingeneral of certain novel details of construction and combination ofparts hereinafter fully described, illustrated in the accompanyingdrawings, and specifically claimed.

In the accompanying drawings, like characters of reference indicate likeparts in the several views, and

Figure 1 is a side elevation of a screen constructed in accordance withthis invention.

Fig. 2 is a section on the line 22 of Fig. 1.

Fig. 3 is a section on the line 33 of Fig. 1.

Fig. 4 is a detail view of a portion of one of the members showing themanner of slitting the same in order to form the completed member.

In carrying out the objects of the invention as disclosed in the presentdrawings there is provided a screen composed of four separate cornersections 10, 11, 12 and 13. Two of these sections are made of tubularmetal as indicated at 11 and 13 and the tube is so arranged as to berectangular in gen eral contour but certain portions thereof areSpecification of Letters Patent.

bent inward to provide oppositely disposed grooves 14 to receivecoacting portions of the adjoining members. The remaining members 10 and12 are made of tubular metal but the metal is slit along a line 15longitudinally of each branch and then split transversely as at 16 so asto provide two tongues which are downwardly bent as at 17, said tonguesconstituting inturned edges on flange portions 18. It is to be notedthat certain portions of the metal in the members 10 and 12 are left atthe corner as at 19 so as to support the parts in proper spacedrelation. Each of the corner members or corner sash sections justdescribed is provided with a separate piece of wire screen fabric asindi cated at 20 and this fabric isfree from all of the sections exceptits own corner section so that the different pieces of fabric may slide,

one on the other, when the screen is assem-v bled. It is to be notedthat the device when assembled is so arranged that the inturned edges 17enter the grooves 14 of the coacting members so that the two members canslide one on the other.

Now by this arrangement there is provided four corner screen sectionswhich are slidably interlocked and each of which has its own appropriatesection of screen fabric so that the device may be enlarged, eithersidewise or vertically and thus be made to accommodate any size ofwindow opening within certain limits, these being from the size whentotally collapsed to the size of the device when totally expanded inboth directions.

There has thus been provided a simple and efficient device of the kinddescribed and of the character specified.

It will be obvious that many minor changes may be made in the form andconstruction of this invention without departing from the materialprinciples thereof. It is not therefore desired to confine the inventionto the exact form herein shown and described, but it is wished toinclude all such as come properly within the scope claimed.

Having thus described the invention, what is claimed as new, is

A collapsible screen comprising four rectangular sheets of screenfabric, an L-shaped section connected to the outer edges of each.

sheet, a pair of said sections being rectan gular in cross section andhaving girooves In testimony whereof, I aflix my signaformed uponopposite sides thereof, the ture, in the presence of two Witnesses.
